Except that's not what's likely to happen. Even if 100% WFH is the official policy, people will be leaned on to come into the office. And as the number of people working remotely shrinks, that will only get worse, because it's very hard to be an outlier when everyone else is communicating real-time face to face.
I've seen all-remote, all-local, and mixed environments. I just don't have faith that mixed environments work well, but every situation is different.
Of course, when I stated I'm less than happy about that, they claimed it's very safe. Yet all workers are traveling by bus and masks are not mandatory.
Aside: genuine bona fide former bench scientist who used to work in a hot lab here. I stopped working in hot labs because the safety practices of my coworkers terrified me. Many of them are dead of cancer now, decades later. While there's no strong evidence for it, I cannot entirely dismiss the lab Leak theory here based on my prior experience working with fellow scientists and their cavalier attitudes towards safety. Had I stayed I think I would have lost my mind.
During the peak of the pandemic I was still going to my office at Oxford University. However, this other institution I'm potentially joining has much more relaxed safety measures.
I think having a low-density office is a must even if there is no pandemics. I want to be productive, and I don't want to be surrounded by tens of coughing people during the flu season. It's just commonsense.
To that end, opening up all the corporate offices for those that feel the need to be in the office once again whilst 100% allowing work from home seems the best of both worlds. We have vaccines. But we also have a rapidly evolving virus and a perfect storm right now for it to evolve further. I'm betting on the virus to win this one in the short-term. But I'm also betting in the long term that it's doomed, fortunately.
